Test Driver Ratings & Comments

Acceleration commentsIt was nearly impossible to detect any traction control -- rather it gave more power the further it was driven.
Braking ratingGood
Braking commentsN/A
Handling ratingExcellent
Handling commentsNon-defeat VSA (Vehicle Stability Assist) means playing within the prescribed limit which turns out to be rather generous considering Toyota's conservative history with such systems. As smooth as one can be with the steering wheel is the least disruptive and fastest way through. Exceptionally well-balanced grip fore and aft. Steering is a bit numb but I like the ratio at speed.
